A preliminary survey of the association of Pseudomonas aeruginosa with commercial whirlpool bath waters.

Conditions in commercial whirlpool baths were investigated and populations of Pseudomonas aeruginosa surveyed. Conditions generally favored growth, and P. aeruginosa was demonstrated in 62.5 per cent of 24 samples of bath waters surveyed. Serotype 11, implicated in outbreaks of skin rash among bathers at whirlpool baths, was demonstrated most frequently, being isolated from 30 per cent of the 24 survey samples, and from 70 per cent of 20 additional samples from a single bath sampled on two days.
